Abstract

The invention discloses a power grid temperature monitoring method based on a distributed type fiber bragg grating, comprising the following step of: arranging two platforms: a workstation platform and an office platform, wherein the workstation platform comprises a data processing module, a temperature monitoring module, an administrator module, an acousto-optic early-warning module, a laser filter control module, an AD (Analog to Digital) acquisition module and an optical debugging module; the office platform comprises an information integration module, a site information module, a real-time monitoring module, a remote management module, a history module, a report preprocessing module and a report exhibition module; and the workstation platform and the office platform share a databank and a memory module. The invention establishes a uniform real-time communication system and an integrated temperature and environment automatic monitoring system and realizes the concentration exhibition and the substation exhibition of temperature monitoring objects of a high-voltage device and the exhibition of real-time data curve and a graph report.

Description

technical field [0001] The invention relates to the field of fiber grating sensing, in particular to a temperature monitoring method based on distributed fiber grating power grids. Background technique [0002] As early as 1978, when Hill KO and others of the Canadian Communication Center first used the standing wave writing method in the germanium-doped optical fiber to make a fiber Bragg grating (FBG), the United States, Europe and other countries and regions became the scientific research center for fiber grating sensors and sensing technology. and technology development hotspots. [0003] Fiber Bragg grating sensing technology is a high-tech photoelectric sensing technology that has been applied and developed very rapidly in recent years. class of physical quantities. [0004] Since fiber grating sensing technology has achieved many key technological breakthroughs in engineering applications, this technology has been successfully applied to the safety detection of buil...
